We had a strategy and everything!

My group of four that play together all the time just decided the Hard mode of the Incursion seemed easy enough to try Challenging. We discussed our gear, who was running what skills and where we were going to play each wave.

We moved into the sewers, threw down a support station, then each one of us proceeded to get one tapped dead by a shotgun.

I just picked myself up off the floor from laughing.

Enjoy.
